What the publisher says

From the U2 MCP Server repository's README, as published. We do not edit it. Read it on GitHub

u2-mcp

<!-- mcp-name: io.github.bpamiri/u2-mcp -->

Connect Claude to your Universe/UniData database using natural language.

u2-mcp is an MCP server that lets AI assistants like Claude query and interact with Rocket Universe and UniData MultiValue databases. Ask questions in plain English and get real answers from your data.

The first MCP server for the Pick/MultiValue database family.

What Can You Do With This?

Instead of writing RetrieVe queries, just ask Claude:

How It Works

┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
│  Claude Desktop │◄───►│     u2-mcp      │◄───►│ Universe/UniData│
│  (You ask here) │     │  (Translates)   │     │   (Your data)   │
└─────────────────┘     └─────────────────┘     └─────────────────┘
  1. You ask Claude a question about your database
  2. Claude calls u2-mcp with the appropriate tool
  3. u2-mcp queries your Universe/UniData server
  4. Results come back through Claude in a readable format
